The files in this folder contain data to form the image of coronal hole position and polarity on the solar surface. The sub folder name refers to the synoptic maps used to generate results. The date of the data is marked in the beginning of the file name. E.g., 2018030600CH_SPH.PLT is the distribution of the coronal hole on 2018/03/06. 

ADAPT provide an ensemble of 12 maps. Solutions obtained from each ensemble member are put in separate folders in ./ADAPT/. 

These datas are saved using ASCII. These files can be opened directly by Tecplot 2009 or later versions. 

Lines 1-3 are the Tecplot header. The data begin from line 4. 
Column 1: x coordinate 
Column 2: y coordinate 
Column 3: z coordinate 
Column 4: Coronal hole indicator. 
          0-closed region; 
          1-coronal hole with positive polarity (Br>0) 
		  -1-coronal hole with positive polarity (Br>0)
